BARBED METALLIC FENCING.

SPECIFICATION forming part of Letters Patent No. 446,557, dated February17, 1891.

Application filed June 10,1889.

To all whom, it may concern.-

Be it known that I, THOMAS V. ALLIs, a citizen of the United States, andaresident of New York city, in the county and State of New York, haveinvented new and useful Improvements in Barbed Metallic Fencing, ofwhich the following is a specification.

My invention relates to barbed metallic fencing consisting of a plainflat strip having integral barbs projecting at intervals along one edge;and it consists of such strips made with two laterally-projecting barbsintermediately to A-shapetl barbs projecting in the plane of the stripin a simple arrangement, by which such laterally-projecting barbs aremade available between the barbs of the other form as usually madewithout in any manthus providing such strips with the additionallaterally-projecting barbs to make more formidable and effective stripsfor localities where needed, all as hereinafter fully described,reference being made to the accompanying drawings, in which- Figure 1 isa side view of the strip, showing the manner in which it is cut to formthe /\-shaped barbs and preparatory to the bending of thelaterally-projecting barbs. Fig. 2 is an edge view of the same with theintermediate barbs bent laterally,and Fig. 3 is aside view of the barbedand twisted strips in the complete form.

Barbed strips, as (it, having integral A- shaped barbs b at intervalsalong one edge have been made before with plain straight orsliglitly-curved edges between the bases of the barbs. I now make suchstrips with the prominent convex portions intermediate to such barbsshown on Fig. 1, and slit the same each way from the bases of the barbsnearly which I then bend laterally to the strips, and preferably inalternately oppositedirections, and thus produce such barbsintermediately to the others, and so that when the strip is twisted, asit generally will be, and as I have represented it in Fig. 3, theintermediate Serial no. 313,780. (No model.)

jecting in the plane of the strip and from the same edge, the spacesbetween the barbs being greater than the width of the A-shaped barbs atthe base, substantially as described.

2. The improved barbed fencing consisting of a plain fiat strip havingpairs or couples of laterally projecting barbs at intervals along oneedge, and points intermediate to said pairs or couples projecting fromthe same edge in the plane of the strip, the spaces between the barbsbeing greater than the width of the /\-shaped barbs at the base,substantially as described.

3. The improved barbed fencing having the integral laterally-proj ecting barbs (Z intermediately to the integral A-shaped barbs 1), projectingin the plane of the strip and fromthe same edge, said strip beingtwisted, the spaces between the barbs being greater than the width ofthe A-shaped barbs at the base, substantially as described.

at. The improved barbed fencing-strip having the integral /\-shapedbarbs projecting in the plane of the strip, and laterally-projectingbarbs on the same edge in the order of two of said laterally-projectingbarbs to one of the said A-shaped barbs, the spaces between the barbsbeing greater than the Width of the A-shaped barbs at the base,substantially as described.

In testimony that I claim the foregoing my invention I have signed myname, in pres ence of two witnesses, this 8th day of June, 1889.

THOMAS V. ALLIS.
